SAFEGUARD FOR RAILWAY FOG-SIGNALS.

. SPECIFICATION forming part of Letters Patent No. 423,570, dated March 18, 1890.

Application filed October 1 1889.

.T0 at whom it may coiwern:

Be it known that we, JAMES PARSONS, of Acton Vale, in the county of Bagot, and GEORGE LOWE, of thecity of Montreal, in the district of Montreal, both in the Province of Quebec, Canada, have jointly'invented a certain new and useful Improved Safeguard for Railway Fog-Signals; and we do hereby declare that the following is a full, clear, and exact description of the same.

Our invention has for its object to prevent the displacement of fog-signals by the action upon the rail on which they are laid of the scraper, broom, or any of the usual devices secured to the locomotive in front of the wheels for the purpose of removing obstructions from the track, and thereby obviating the danger incurred from the removal of the signals with such obstructions.

The guard,which we place upon one of the lines of rail to insure. that the fog-signal shall remain in place, is composed of a plate laid loosely on the head of the rail, with a downwardly-projecting flange on the inner side of the rail, and 011 the outside a small flange at both ends, a thumb-screw passing through the one at the rearend, so as to furnish a fulcrum, and the end o' f the one in front being turned up, so as to' fafford a grip and to facilitate the raising of-" that end for I the purpose of inserting underneath it the fog-signal. The insertion under the guard of the detonator, torpedo, or other signal will raise the forward end, clamping down the rear end or that with which the wheel first comes in contact. So soon as the wheel has passed over the signal and exploded it the top plate of the guard will lie horizontally on the rail, and the whole device may, if desired, be shifted along the track to any other spot at which it is desired to place a signal, or else removed.

For full comprehension of the invention reference must be had to the annexed drawings, in which- Figure l is a perspective view of our guard;

Fig. 2, a perspective view of the invention in place on the rail with the signal inserted;

Serial No. 325,730. (No model.)

Fig. 3,'a longitudinal sectionof guard lying on rail, and Fig. 4. an end view with rail in secthe rail, feather-edged, preferably, at both ends, A being a flange projecting downward on the inside.

B is a lug projecting downward from A on the outside of the rail, B being a thumbscrew working through same and-serving as a fulcrum to bear against the under edge of the top flange, and O is a lug at the other end of it with turned-up end 0.

The whole guard is laid on and slipped along the rail to the point desired. The front end of the guard A is then raised by the turned-up end O of O and the detonator, torpedo, or other signal D placed under the guard just behind the lug O, as shown in Fig. 2, thus bringing the rear feather-edge a closely in contact with the rail, the thumb-screw B affording the fulcrum-point, looking it firmly in place and allowing the wheels to pass over it without jar. As soon as the signal is ex ploded the apparatuslies on the rail and can be moved along to aniy other point on the rail or removed. -I

\Vhat we claim is as li ollowsz 1. In a safeguard for railway fog-signals, the combination, with a plate adapted to hear at one point on the top of the rail and at an other point on the explosive resting on such rail, of means for locking such plate in place and preventing its displacement.

2. A safety-guard for railway fog-signals, composed of a flanged plate lying on the rail and a thumb-screw passing through 'the flange and acting as a fulcrum, said guard being locked in place by the insertion of the signal under its forward end, all as herein described.
